Müller F.: Hygrobiella laxifolia (Hook.) Spruce – eine neue Lebermoosart für die Tschechische Republik, 10–13Hygrobiella laxifolia (Hook.) Spruce – a new liverwort of the Czech RepublicAbstract: Hygrobiella laxifolia (Hook.) Spruce was recorded for the first time in the Czech Republic. The three new occurrences lie in two valleys of the National Park Bohemian Switzerland (České Švýcarsko) and the adjacent Protected Landscape Area Labské pískovce and extend thus the known distribution area in the Saxonian part of the Elbe Sandstones. All records were made on sandstone boulders in periodically dried-up streams.

Vondrák J.: Příspěvek k poznání rozšíření druhu Caloplaca demissa v Čechách, 24–27Notes on the distribution of Caloplaca demissa in Bohemia, Czech RepublicAbstract: Previously known and present distributions of Caloplaca demissa in Bohemia are discussed and summarized. Recent field surveys revealed much wider distribution of the species than has been supposed so far. Its altitudinal maximum reaches 700 m in the Doupovské hory Mts (Western Bohemia). Rocks in river valleys and rocky slopes beneath medieval castles and ruins often support this species.
